ASTM D976 / D4737 – Cetane Index

It may be employed for asstm cetane number where the quantity of sample is too small for an engine rating. Generally, it has been found that use of Test Method D results in less offset than use of Test Method D, but there can be specific cases where this is not true. EPA to control diesel fuel aromatics concentrations via a 40 Calculated Cetane Index minimum is based on the correlation between Test Method D and aromatics concentration.
